Bismuth Properties, Uses, Symbol, & Facts Britannica
WebBismuth is a chemical element with atomic number 83 which means there are 83 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the … Bismuth (83Bi) has 41 known isotopes, ranging from Bi to Bi. Bismuth has no stable isotopes, but does have one very long-lived isotope; thus, the standard atomic weight can be given as 208.98040(1). Although bismuth-209 is now known to be radioactive, it has classically been considered to be a stable isotope … Meer weergeven 1. ^ Bi – Excited nuclear isomer. 2. ^ ( ) – Uncertainty (1σ) is given in concise form in parentheses after the corresponding last digits. 3. ^ # – Atomic mass marked #: value and uncertainty derived not from purely … Meer weergeven Bismuth-213 ( Bi) has a half-life of 45 minutes and decays via alpha emission.
